2. Superstatic 449
The compact heat meter with the fluidic
oscillation measuring principle
The consistent further development
The new compact heat and cooling meter
Superstatic 449 is the consistent further
development that successfully applies the
fluidic oscillation measuring principle that
established itself in the recent years, with its
convincing measuring accuracy and measu-
ring stability.
The Superstatic 449 is based, like the well-proven Superstatic 440,
on the static measuring principle of the fluidic oscillation.
All the advantages and innovative features of the fluidic oscillation
are embedded in a new compact form for low flows from
qp 0.6 – qp 2.5 m3/h and combined with the use of modern materials
and Swiss precision.
The heat meter Superstatic 449 is a split device with a detachable
multifunctional modular integrator with a large variety of communication
modules. This allows a wide field of applications and an easy integration
in any district heating, district cooling or building management system.

3. Superstatic 449
The compact static heat meter with
the unique measuring principle
Superstatic 449-the compact heat meter that uses the unique fluidic
oscillation measuring principle.
The principle of the fluidic oscillation was developed by Sontex to its
perfection and ensures a stable and precise measuring in a robust and
reliable design.
The concept of the Superstatic 449 is designed that it can be easily
enhanced in the future, either the flow sensor or the integrator.
The static heat meter Superstatic 449 is available with battery power or
several different mains power supplies. The Superstatic 449 meets the
requirements of the European Measuring Instruments Directive MID
2004/22/EC and is a class 2 heat meter according to EN 1434.
Main features
The Superstatic 449 heat and cooling meter is optimised to measure the
consumption of thermal energy in any district heating, district cooling or
building management system for the individual billing of thermal energy
cost and can be easily integrated in any Smart Metering environment.

Description of
the measuring principle
In the oscillator the liquid is directed
to a nozzle and accelerated to a jet
(Oscillating jet). Opposite of the nozzle
the jet is redirected by a separator to
the left or right into a channel that
leads to the measuring head with a
piezoelectric sensor. The pressure of
the liquid on the sensor generates an
electrical pulse. The liquid flows back
to the pipe through a return loop and
redirects the jet into the other channel
where the action is repeated and flui-
dic oscillation is created.
The frequency of the fluidic oscillation,
i.e. the generated electrical pulses by
the sensor, is linear proportional to the
flow thus the flow can be calculated.
A positive side effect is a self-cleaning
of the oscillator due to the increased
speed of the oscillating jet.
